Welcome to the small circle of individuals who,
if we are to be absolutely precise, demand slightly more
of a watch than absolute precision. Appreciation of a
watch is more than mere appreciation of the correct time.
It is enthusiasm for an ingenious idea. For the interplay
between precision and imagination. Between time and
timelessness. Between boundaries and infinity. Between
laws to which the entire world is subject, and taste, which
cannot be dictated to anyone. That is why, since 1868, we
have been devoting rather more of our time to watches
that must not only run with absolute precision but which
also, with every passing second, exert a fascination with
the great achievements of master craftsmanship: a fasci-
nation with new inventions of a technical, material or for-
mal nature, even if they are concealed in minute details
that are perhaps not even visible. You are now the owner
of a beautiful new example of this IWC tradition. We
would like to congratulate you on your choice and send
you our best wishes for the time you will spend with your
watch, which perhaps cannot be described with any
greater accuracy than it is here.
IWC Management

The technical refinements
of the Aquatimer Chronograph
Your IWC watch shows you the time in hours, minutes
and seconds, together with the date. You can use
the integrated chronograph to measure any period in
seconds, minutes and hours. Stop times can be added
together. Dive time is read off on the external rotating
bezel, which for safety reasons can only be turned
anticlockwise. The mechanical movement with auto-
matic winding has 40 jewels (synthetic rubies) and
a power reserve of approximately 68 hours when fully
wound. Your Aquatimer Chronograph is shockproof,
water-resistant 12 bar and protected by sapphire glass
of hardness grade 9 on the Mohs’ scale. To ensure that
this extraordinary watch continues to perform faultlessly
in the future, it is essential to observe a few important
operating instructions.

Normal position
This watch has a screw-in crown. Screwing the crown
in to its normal position (X) prevents inadvertent adjust-
ment of the time or date and acts as a double seal
against ingress of water into the case. To release the
crown, unscrew it by turning it to the left, where it auto-
matically assumes position 0, the winding position.
By depressing the crown in position X and turning it to
the right at the same time, it is screwed down firmly
again and secured.

Winding position
With the crown in the winding position (0), you can also
wind the automatic movement by hand. A few revolutions
of the crown are enough to start the movement. How-
ever, it is better to wind the movement fully by turning the
crown through about 40 revolutions. This will ensure
maximum accuracy and a power reserve of about
68 hours, even if you are not wearing your watch.
Date setting
If a month has fewer than 31 days, you will need to set
the date manually to the first day of the following month.
Pull the crown out to position 1. You can now set the date
by turning the crown to the right (rapid advance). You
should not use the rapid advance function between 8 pm
and 2 am because the movement automatically ad-
vances the date during this period.

Time setting
Pull the crown out to position 2. This will stop the move-
ment. To set the time accurately to the second, it is best
to stop the movement as the seconds hand reaches 60.
Now move the minute hand a few minutes beyond the
time to which you wish to set the watch. Then position
the minute hand by moving it gently backwards until it is
exactly above the correct minute stroke. This ensures
that the minute hand begins to move immediately when
you restart the movement. To start the seconds hand,
push in the crown to position 0. When setting the time,
please be aware of the date change, which always takes
place at 12 midnight. If this change has already taken
place at 12 noon, you must move the hands forward by
12 hours.
Setting your watch correctly
To set your watch correctly, proceed as follows:
• Release the crown by turning it to the left.
• Wind the movement until it is fully wound (about
40 revolutions of the crown).
• Pull the crown out to position 1.
• Turn the crown to the right to advance the date display
a day at a time. Set the display to yesterday’s date.

8 | 9
• Pull the crown out to position 2. This will stop the
movement. To set the time accurately to the second,
it is best to stop the movement as the seconds hand
reaches 60.
• Turn the hands forward until the date display changes
to today’s date. The hands will now be positioned
between 12 midnight and 1 am.
• Now turn the hands forward to the correct time. If you
are setting the watch in the afternoon, you must turn
the hands past 12 noon again.
• Push the crown back to position 0 to start the watch
movement.
• Now push the crown to position X and secure it by
simultaneously turning it to the right.
Important: Although the watch is water-resistant in
positions 0, 1 and 2, the crown should always be
screwed in again for normal use (position X).

Reading the time in the dark
The dial, the hour and minute hands as well as the
marking on the rotating bezel of your watch have lumi-
nescent elements that allow you to read the time
effortlessly even in total darkness. The two luminescent
elements at 12 o’clock serve as a reference point.
Reading the chronograph
Chronograph seconds hand: The scale for the central
chronograph seconds hand runs around the edge of the
dial.
Minute and hour counters: The subdial at 12 o’clock
has two hands, which run continuously and show the
elapsed time on a 12-hour and a 60-minute scale. The
hour and minute counters can be read like a standard
analogue time display. In other words, one revolution
of the minute counter is equal to 60 minutes, and one
revolution of the hour counter is equal to 12 hours.

Using the chronograph
Start: To start the chronograph, press the start/stop
button.
Flyback: You can start recording a new time immedi-
ately, even when the chronograph is running. With the
chronograph running, simply depress the reset/flyback
button fully as far as it will go. All three chronograph
hands are reset to zero, and a new measurement is
started as soon as the button is released.
Stop: To stop the running chronograph, press the
start/stop button again.
Reset: Depress the reset/flyback button fully as far
as it will go. This will reset all the chronograph hands
to zero.
Aggregate time recording: You can add stop times to-
gether by pressing the start/stop button again after the
first measurement instead of the reset/flyback button.

Marking the start of a dive
The triangle on the rotating bezel can be aligned with
the minute hand by turning the rotating bezel anticlock-
wise. The desired point in time (e. g. the time of entering
the water at the start of the dive) can be set in this way.
You can read off the elapsed time (e. g. the duration
of the dive) on the rotating bezel. For safety reasons, the
rotating bezel can only be rotated in an anticlockwise
direction. The rotating bezel is indexed audibly and per-
ceptibly in steps of one minute, and it is also legible in
the dark thanks to the luminescent markings.
If you are planning to use the watch to time dives,
you should have certification as an open water
diver and have the water-resistance of your watch
checked regularly by an IWC service centre.
Cleaning the watch after diving
After diving – and especially after diving in seawater –
you should rinse your watch under running mains water.
This will prevent salt incrustation on the case, bracelet
and clasp.

Water-resistance
The water-resistance of IWC watches is stated in bar
and not in metres. Metres, which are often used else-
where in the watch industry to indicate water-resistance,
cannot be equated with dive depth because of the test
procedures that are frequently used. Water-resistance
shown in metres provides no indication as to actual use
of the watch in the presence of moisture and wetness,
and in or under water. Recommendations for use in con-
nection with the water-resistance of your watch can be
found on the Internet at www.iwc.com/water-resistance.
Your authorised IWC Official Agent will also be pleased
to provide you with information.
To ensure that your watch continues to function per-
fectly, you should have it checked by an IWC service
centre at least once a year. Your watch should also be
tested after exposure to unusually harsh conditions.
If the tests are not carried out as stipulated, or if the
watch is opened by unauthorised persons, IWC will
accept no warranty or liability claims.
Recommendation: Your authorised IWC Official Agent
must carry out a water-resistance test whenever your
IWC watch is opened and serviced.

Changing between different types of bracelet
Your IWC watch has a bracelet quick-change system*
that enables you to change the bracelet quickly and
simply, without the use of tools.
To remove the bracelet, use your
thumb to push down the retaining
lever (1) on the underside of the
horns.
While holding the lever down, slide
the connecting link out vertically
from the underside of the case (2).
* The Aquatimer bracelet quick-change system has been developed
by IWC under a patent license from Cartier.

To attach the bracelet, push down
the two sides of the horns vertically
towards the lower side of the case
and into the recesses (3) until you
hear and feel the retaining lever
engage.
When attaching the bracelet, you must ensure that
the horns are securely engaged to prevent the bracelet
coming off your arm unintentionally.
Servicing your Aquatimer Chronograph
Although the parts in this watch are all manufactured
from top-quality materials, a number of components
are subject to natural wear and tear. It is particularly im-
portant to ensure that the points at which wear occurs
are always well-lubricated and that oil contaminated by
metal abrasion is regularly removed. For this reason,
we recommend that you have your watch serviced
approximately every five years. Please contact an
authorised IWC Official Agent or send your watch
directly to the IWC Customer Service Department in
Schaffhausen.
Effective from January 2009.
